Der buchsenseitige Endbereich ist hierbei der Endbereich des Gehäuses bzw. der Endbereich der Leiterplatte, der beim Einstecken des Steckers in eine Buchse vorne liegt. In anderen Worten wird beim Verbinden des Steckers mit der Buchse der buchsenseitige Endbereich des Gehäuses und der buchsenseitige Endbereich der Leiterplatte, somit auch der buchsenseitige Endbereich des Steckers, in die Buchse eingesteckt. Der kabelseitige Endbereich des Gehäuses bzw. der kabelseitige Endbereich der Leiterplatte ist der Endbereich des Gehäuses bzw. der Leiterplatte, der in Einsteck-Richtung dem buchsenseitigen Endbereich des Gehäuses bzw. der Leiterplatte gegenüber liegt. An seinem kabelseitigen Endbereich nimmt das Gehäuse das zumindest eine Verbindungskabel auf, und die Litzen des Verbindungskabels werden mit den Litzen-Kontakten am kabelseitigen Endbereich der Leiterplatte elektrisch leitend verbunden. Die Längsachsen des Steckers, des Gehäuses sowie der Leiterplatte verlaufen zwischen dem buchsenseitigen und kabelseitigen Endbereich des Steckers, des Gehäuses und der Leiterplatte und sind zueinander parallel. Die Längsachsen des Steckers, des Gehäuses und der Leiterplatte sind ebenso parallel zu der Einsteckrichtung.The socket-side end region is here the end region of the housing or the end region of the printed circuit board, which is located at the front when inserting the plug into a socket. In other words, when connecting the plug to the socket, the socket-side end region of the housing and the socket-side end region of the printed circuit board, and thus also the socket-side end region of the plug, are plugged into the socket. The cable-side end region of the housing or the cable-side end region of the printed circuit board is the end region of the housing or of the printed circuit board which lies opposite the socket-side end region of the housing or printed circuit board in the plug-in direction. At its cable-side end portion, the housing accommodates the at least one connection cable, and the strands of the connection cable are electrically conductively connected to the stranded contacts on the cable-side end region of the circuit board. The longitudinal axes of the plug, the housing and the circuit board extend between the socket-side and cable-side end portion of the plug, the housing and the circuit board and are parallel to each other. The longitudinal axes of the plug, the housing and the printed circuit board are also parallel to the insertion direction.

Die Leiterplatte kann auch als PCB (printed circuit board) oder Platine bezeichnet werden. Bei dem zumindest einen Verbindungskabel kann es sich um ein Netzwerk-Kabel mit einer Vielzahl von Litzen, vorzugsweise mit 6, 7, 8, 9, 10 oder mehr Litzen, handeln. Die einzelnen Litzen des zumindest einen Verbindungskabels können die selbe Litzenstärke aufweisen oder verschiedene Litzenstärken aufweisen. Gängige Litzenstärken für signalübertragende Litzen betrgane zwischen etwa 0.08 mm bis 0.13 mm, insbesondere zwischen etwa 0.10 mm bis 0.12 mm. Gängige Litzenstärken für energieübertragende Litzen betragen zwischen etwa 0.08 mm bis 0.13 mm, zwischen etwa 0.10 mm bis 0.12 mm.The circuit board may also be referred to as PCB (printed circuit board) or board. The at least one connection cable may be a network cable having a plurality of strands, preferably 6, 7, 8, 9, 10 or more strands. The individual strands of at least one connection cable, the have the same strand thickness or have different strand thicknesses. Common strand thicknesses for signal-transmitting strands betrgane between about 0.08 mm to 0.13 mm, in particular between about 0.10 mm to 0.12 mm. Common strand thicknesses for energy-transmitting strands are between about 0.08 mm to 0.13 mm, between about 0.10 mm to 0.12 mm.

Es können auch Litzen von zwei oder mehr Verbindungskabeln mit den Litzen-Kontakten der Leiterplatte elektrisch leitend verbunden werden, wobei jeweils eine Litze einem Litzen-Kontakt zugeordnet sein kann. Insbesondere kann es sich bei einem Verbindungskabel um ein Netzwerk-Kabel handeln und bei einem zweiten Verbindungskabel um ein Stromkabel.It is also possible to connect strands of two or more connection cables to the strands contacts of the circuit board in an electrically conductive manner, it being possible in each case for one strands to be associated with one strands contact. In particular, a connection cable may be a network cable and a second connection cable may be a power cable.

Der elektrisch leitende Kontakt der Buchsen-Kontakte mit den Kontaktelementen der Buchse kann dadurch hergestellt werden, dass die Buchsen-Kontakte mit den Kontaktelementen der Buchse mechanisch in Kontakt treten. Hierbei können einzelne Buchsen-Kontakte vorzugsweise mit einer Kraft von etwa 0.1 N bis 1 N , insbesondere von etwa 0.3 N bis 0.8 N gegen die Kontaktelemente der Buchse gepresst werden. Durch den elektrisch leitenden Kontakt können elektrische Ströme bzw. Spannungen sowie Signale als Resultat der Strom- bzw. Spannungsübertragung zwischen den Buchsen-Kontakten und den Kontaktelementen der Buchse übertragen werden.The electrically conductive contact of the socket contacts with the contact elements of the socket can be made by mechanically contacting the socket contacts with the contact elements of the socket. In this case, individual socket contacts can preferably be pressed with a force of about 0.1 N to 1 N, in particular from about 0.3 N to 0.8 N against the contact elements of the bushing. Due to the electrically conductive contact, electrical currents or voltages as well as signals can be transmitted as a result of the current or voltage transmission between the socket contacts and the contact elements of the socket.

Signalübertragende Buchsen-Kontakte und Litzen-Kontakte können ausgelegt sein, ausschließlich elektrische bzw. elektronische Signale zu übertragen. Statt "signalübertragend" können auch die Begriffe "informationsübertragend", "informationsführend" oder "datenübertragend" verwendet werden. Es werden zwar zur Signalübertragung elektrische Ströme über die signalübertragenden Buchsen-Kontakte und Litzen-Kontakte übertragen bzw. es liegen zwar Spannungen an den signalübertragenden Buchsen-Kontakten und Litzen-Kontakten an, vorzugsweise dienen diese jedoch ausschließlich der Signalübertragung. D.h. die signalübertragenden Buchsen-Kontakte und Litzen-Kontakte übertragen keine Energie zur Versorgung von Geräten. Beispielsweise können über die signalübertragenden Buchsen-Kontakte und Litzen-Kontakte Ströme von etwa 0.01 mA bis 1.0 mA insbesondere von etwa 0.1 mA bis 0.5 mA übertragen werden, bzw. können an den signalübertragenden Buchsen-Kontakten und Litzen-Kontakten Spannungen von etwa 1V bis etwa 15 V, insbesondere von etwa 5 V bis 10 V anliegen.Signal transmitting jack contacts and stranded contacts may be configured to carry only electrical or electronic signals. Instead of "signal-transmitting", the terms "information-transmitting", "information-carrying" or "data-transmitting" can also be used. Although electrical currents are transmitted for signal transmission via the signal-transmitting socket contacts and stranded contacts, although voltages are present at the signal-transmitting socket contacts and stranded contacts, these are preferably used exclusively for signal transmission. This means that the signal-transmitting socket contacts and stranded contacts do not transfer energy to power devices. For example, about the currents of about 0.01 mA to 1.0 mA, in particular from about 0.1 mA to 0.5 mA are transmitted, or can at the signal-transmitting jack contacts and stranded contacts voltages of about 1V to about 15 V, in particular signal transmitting female contacts and strands contacts from about 5V to 10V.

Energieübertragende Buchsen-Kontakte und Litzen-Kontakte können ausgelegt sein, ausschließlich Energie für die Energie-Versorgung von Geräten, beispielsweise Netzwerk-Geräten oder Rechnern, zu übertragen. Bei der Energie handelt es sich um elektrische Energie, so dass auch von "stromübertragenden", "stromführenden", "spannungsübertragenden" oder "spannungsführenden" Buchsen- und Litzen-Kontakten gesprochen werden kann. D.h. die energieübertragenden Buchsen-Kontakte und Litzen-Kontakte übertragen vorzugsweise keine Signale, Daten oder Informationen. Beispielsweise können über die energieübertragenden Buchsen-Kontakte und Litzen-Kontakte Ströme von etwa 1.5 A bis etwa 2.5 A, insbesondere etwa 2.1 A bei einer Temperatur von etwa -30°C bis etwa 90°C, bevorzugt etwa - 10°C bis etwa 80°C, weiter bevorzugt bis etwa 70° C, insbesondere bei etwa 70°C übertragen werden, bzw. können an den energieübertragenden Buchsen-Kontakten und Litzen-Kontakten Spannungen von etwa 30 V (DC) bis etwa 70 V (DC) bevorzugt 40 V (DC) bis etwa 60 V (DC), insbesondere von etwa 50 V (DC) bzw. von etwa 10 V (AC) bis etwa 50 V(AC), bevorzugt von etwa 20 V (AC) bis etwa 40 V (AC), insbesondere von etwa 35 V (AC) anliegen.Power transmitting jack contacts and stranded contacts may be configured to only transfer energy for powering devices such as network devices or computers. The energy is electrical energy, so that it is also possible to speak of "current-carrying", "current-carrying", "voltage-transmitting" or "live" socket and stranded contacts. That the energy transmitting jack contacts and strands contacts preferably do not transmit signals, data or information. For example, currents of from about 1.5 A to about 2.5 A, in particular about 2.1 A, at a temperature of about -30 ° C. to about 90 ° C., preferably about -10 ° C. to about 80, can be obtained via the energy-transmitting jack contacts and stranded contacts C., more preferably up to about 70.degree. C., in particular at about 70.degree. C., or voltages of about 30 V (DC) to about 70 V (DC) may be preferred 40 on the energy-transmitting socket contacts and stranded contacts V (DC) to about 60 V (DC), in particular from about 50 V (DC) or from about 10 V (AC) to about 50 V (AC), preferably from about 20 V (AC) to about 40 V ( AC), in particular of about 35 V (AC) abut.

Jeder signalübertragende Buchsen-Kontakt kann über eine Leiterbahn der Leiterplatte mit einem zugeordneten signalübertragenden Litzen-Kontakt elektrisch leitend verbunden sein. Elektrisch leitend verbunden bedeutet hierbei, dass ein Signalaustausch zwischen Buchsen-Kontakt und Litzen-Kontakt möglich ist. Bei den Leiterbahnen der Leiterplatte kann es sich um geätzte Kanäle auf der Leiterplatte handeln. Die einzelnen Leiterbahnen der Leiterplatte sind vorzugsweise untereinander elektrisch isoliert.Each signal-transmitting socket contact can be electrically connected via a conductor track of the printed circuit board with an associated signal-transmitting stranded contact. Electrically connected means in this case that a signal exchange between female contact and stranded contact is possible. The printed conductors of the printed circuit board may be etched channels on the printed circuit board. The individual printed conductors of the printed circuit board are preferably electrically insulated from one another.

Vorteilhafterweise kann durch den Stecker gemäß diesem Aspekt der Erfindung die Signalqualität des zu übertragenden Signals verbessert werden, und die Leistungsfähigkeit des Steckers verbessert werden. Dies wird zum einen durch die Trennung zwischen den signalübertragenden Kontakten und den energieübertragenden Kontakten erreicht, da so die jeweiligen Kontakte hinsichtlich ihrer Funktion optimal ausgelegt werden können. Darüber hinaus wird das zu übertragende Signal nicht durch die zu übertragende Versorgungsspannung bzw. durch den zu übertragenden Versorgungsstrom beeinflusst. Auch können die hohen Temperaturen bzw. die Wärme, die durch die Übertragung der Versorgungsenergie entstehen kann, gezielt von den signalübertragenden Kontakten und Leitern ferngehalten werden bzw. besser abgeführt werden. Ferner ist es durch die getrennten energieübertragenden Kontakte möglich, Geräte mit höheren Strömen bzw. Spannungen zu versorgen. Weiter wird durch das Vorsehen der Leiterplatte die Signalqualität verbessert, da die Leiterbahnen auf der Leiterplatte ausgelegt bzw. angeordnet werden können, um gegenseitige Störeinflüsse zwischen den Leiterbahnen zu minimieren. Dies ist möglich, da die Leiterbahnen auf der Leiterplatte genauer geführt werden können als Litzen.Advantageously, by the plug according to this aspect of the invention Signal quality of the signal to be transmitted can be improved, and the performance of the connector can be improved. This is achieved on the one hand by the separation between the signal-transmitting contacts and the energy-transmitting contacts, as this way the respective contacts can be optimally designed with regard to their function. In addition, the signal to be transmitted is not influenced by the supply voltage to be transmitted or by the supply current to be transmitted. Also, the high temperatures or the heat that may be caused by the transmission of the supply energy can be selectively kept away from the signal-transmitting contacts and conductors or better dissipated. Furthermore, it is possible by the separate power-transmitting contacts to supply devices with higher currents or voltages. Furthermore, the signal quality is improved by the provision of the printed circuit board, since the printed conductors can be laid out or arranged on the printed circuit board in order to minimize mutual interference between the printed conductors. This is possible since the printed conductors on the printed circuit board can be guided more precisely than strands.

Vorzugsweise kann jeder energieübertragende Buchsen-Kontakt mittels eines Verbindungsleiters mit einem zugeordneten energieübertragenden Litzen-Kontakt elektrisch leitend verbunden sein, wobei jeder Verbindungsleiter an der Oberfläche der Leiterplatte angeordnet sein kann.Preferably, each energy-transmitting socket contact can be electrically connected by means of a connecting conductor with an associated energy-transmitting stranded contact, wherein each connecting conductor can be arranged on the surface of the printed circuit board.

Vorteilhafterweise kann ein Verbindungsleiter mit einem größeren Querschnitt als der Querschnitt einer Leiterbahn der Leiterplatte ausgeführt werden, so dass die elektrische Leitfähigkeit erhöht wird und höhere Ströme bzw. Spannungen übertragen werden können als über Leiterbahnen einer Leiterplatte. Beispielsweise kann der Verbindungsleiter eine Querschnittsfläche von zwischen etwa 0.1 mm2 bis etwa 0.4 mm2 bevorzugt zwischen etwa 0.15 mm2 bis etwa 0.3 mm2, besonders bevorzugt von etwa 0.25 mm2 aufweisen, wogegen die Leiterbahnen eine Querschnittsfläche von etwa 0.0005 mm2 bis etwa 0.002 mm2, bevorzugt von etwa 0.0009 mm2 bis etwa 0.0015 mm2 besonders bevorzugt von etwa 0.001 mm2 aufweisen können. Außerdem wird ermöglicht, dass die signalübertragenden Kontakte und die energieübertragenden Kontakte gesondert geerdet werden können, und/oder gesondert abgeschirmt werden können.Advantageously, a connecting conductor having a larger cross section than the cross section of a conductor track of the printed circuit board can be designed so that the electrical conductivity is increased and higher currents or voltages can be transmitted than via conductor tracks of a printed circuit board. For example, the connection conductor may have a cross-sectional area of between about 0.1 mm 2 to about 0.4 mm 2, preferably between about 0.15 mm 2 to about 0.3 mm 2 , particularly preferably about 0.25 mm 2 , whereas the conductor tracks have a cross-sectional area of about 0.0005 mm 2 to about 0.002 mm 2 , preferably from about 0.0009 mm 2 to about 0.0015 mm 2, more preferably about 0.001 mm 2 . It also allows the signal transmitting Contacts and the power-transmitting contacts can be grounded separately, and / or can be shielded separately.

Beispielswiese kann der Verbindungsleiter einen im wesentlichen runden oder rechteckigen Querschnitt aufweisen. Besonders bevorzugt ist der Verbindungsleiter ein Draht bzw. drahtförmig.For example, the connection conductor may have a substantially round or rectangular cross-section. Particularly preferably, the connecting conductor is a wire or wire-shaped.

Die Anordnung der Verbindungsleiter auf der Oberfläche der Leiterplatte vereinfacht die Montage des Steckers. Der Verbindungsleiter kann auf der Leiterplatte ohne eine dafür vorgesehene Vertiefung angeordnet sein. Insbesondere kann der Verbindungsleiter auf der Isolierschicht bzw. des Isolierlacks der Leiterplatte angeordnet sein. Die Verbindungsleiter können aber auch getrennt von der Leiterplatte angeordnet sein. Ebenfalls ist es denkbar, dass die energieübertragenden Buchsen-Kontakte über Leiterbahnen der Leiterplatte mit den energieübertragenden Litzen-Kontakten elektrisch leitend verbunden werden bzw. sind.The arrangement of the connection conductors on the surface of the circuit board simplifies the assembly of the connector. The connection conductor can be arranged on the circuit board without a recess provided for this purpose. In particular, the connecting conductor can be arranged on the insulating layer or the insulating varnish of the printed circuit board. However, the connection conductors can also be arranged separately from the printed circuit board. It is also conceivable that the energy-transmitting socket contacts are electrically connected via conductor tracks of the printed circuit board with the energy-transmitting Litzen contacts or are.

Vorzugsweise sind alle Litzen-Kontakte oder eine Teilmenge der Litzen-Kontakte auf einer Seite der Leitungsplatte angeordnet, auf der keine Leiterbahnen ausgebildet sind.Preferably, all of the stranded contacts or a subset of the stranded contacts are disposed on a side of the conductive plate on which no traces are formed.

Leiterplatten weisen üblicherweise eine Oberfläche bzw. Seite auf, die bedruckt ist bzw. Leiterbahnen umfaßt. Die Litzen-Kontakte und ebenso die Buchsen-Kontakte können jedoch auf der Oberfläche bzw. Seite der Leiterplatte angeordnet sein, die nicht bedruckt ist bzw. die keine Leiterbahnen aufweist. In diesem Fall durchdringen die Litzen-Kontakte bzw. die Buchsen-Kontakte die Leiterplatte, um mit den Leiterbahnen bzw. den Verbindungsleitern auf der anderen Seite elektrisch leitend verbunden zu werden bzw. elektrisch verbunden zu sein. Das elektrisch leitende Verbinden kann durch Löten geschehen. Vorteilhafterweise kann durch das Anordnen von Litzen-Kontakten bzw. Buchsen-Kontakten auf einer Seite der Leiterplatte, auf der keine Leiterbahnen ausgebildet sind, der Raum innerhalb des Steckers bzw. des Gehäuses besser ausgenutzt werden, da auf beiden Oberflächen der Leiterplatte Litzen-Kontakte bzw. Buchsen-Kontakte angeordnet werden können.Printed circuit boards usually have a surface or side which is printed or comprises conductor tracks. However, the stranded contacts and also the socket contacts can be arranged on the surface or side of the printed circuit board which is not printed or which has no conductor tracks. In this case, the stranded contacts or the female contacts penetrate the printed circuit board in order to be electrically conductively connected or electrically connected to the interconnects on the other side. The electrically conductive connection can be done by soldering. Advantageously, by arranging stranded contacts or socket contacts on one side of the printed circuit board, on which no printed conductors are formed, the space within the plug or the housing can be better utilized, since on both surfaces the printed circuit board stranded contacts or female contacts can be arranged.

Vorzugsweise weist eine Seite (Unterseite) der Leiterplatte acht signalübertragende Buchsen-Kontakte auf. Weiter vorzugsweise weist die andere Seite (Oberseite) der Leiterplatte zwei energieübertragende Buchsen-Kontakte auf.Preferably, one side (underside) of the printed circuit board has eight signal-transmitting socket contacts. Further preferably, the other side (upper side) of the printed circuit board has two energy-transmitting socket contacts.

Durch die Anordnung von acht signalübertragenden Buchsen-Kontakten auf der Unterseite der Leiterplatte, und somit auch auf der Unterseite des vorderen Endbereichs des Steckers, kann der Stecker eine Buchsen-Kontakt Anordnung eines standardisierten RJ 45 Netzwerksteckers aufweisen. Durch die Anordnung von zwei energieübertragenden Buchsen-Kontakten auf der Oberseite der Leiterplatte, und somit auch auf der Oberseite des vorderen Endbereichs des Steckers, kann der Stecker zusätzlich zwei energieübertragende Kontakte zur Energieversorgung bereitstellen, ohne die standardisierte Ausgestaltung eines RJ 45 Netzwerksteckers wesentlich zu verändern, nämlich mit acht signalübertragenden Buchsen-Kontakten auf der Unterseite und mit zwei energieübertragenden Buchsen-Kontakten auf der Oberseite des Steckers.The arrangement of eight signal-transmitting socket contacts on the underside of the circuit board, and thus also on the underside of the front end portion of the plug, the plug can have a female contact arrangement of a standardized RJ 45 network connector. The arrangement of two power-transmitting socket contacts on the top of the circuit board, and thus also on the top of the front end portion of the plug, the plug can additionally provide two energy-transmitting contacts for power supply, without significantly changing the standard design of a RJ 45 network connector, namely with eight signal-transmitting socket contacts on the bottom and with two energy-transmitting socket contacts on the top of the plug.

Die Oberseite und die Unterseite der Leiterplatte deuten auf die zwei Oberflächen der Leiterplatte, wobei eine Oberfläche oder beide Oberflächen Leiterbahnen aufweisen können. Die Unterscheidung zwischen Oberseite und Unterseite ist vordefiniert und dient der Zuordnung der beiden Oberflächen der Leiterplatte.The top and bottom of the circuit board point to the two surfaces of the circuit board, wherein one surface or both surfaces may have traces. The distinction between top and bottom is predefined and serves to assign the two surfaces of the circuit board.

Vorzugsweise sind die energieübertragenden Buchsen-Kontakte in Richtung der Breitenachse der Leiterplatte relativ zu den signalübertragenden Buchsen-Kontakten außenliegend angeordnet.Preferably, the energy-transmitting socket contacts are arranged in the direction of the width axis of the printed circuit board on the outside relative to the signal-transmitting socket contacts.

Die Richtung der Breitenachse der Leiterplatte ist hierbei die Richtung, in die sich die Leiterplatte in der Breite erstreckt, das heißt quer zur Längsachse der Leiterplatte. Die Breitenachse kann auch als Querachse bezeichnet werden. In anderen Worten sind die signalübertragenden Buchsen-Kontakte zwischen den außenliegenden, energieübertragenden Buchsen-Kontakten auf der Leiterplatte angeordnet. Vorteilhafterweise ermöglicht diese Anordnung, dass die Verbindungsleiter, welche die energieübertragenden Litzen-Kontakte mit den energieübertragenden Buchsen-Kontakten elektrisch leitend verbinden, in Richtung der Breitenachse der Leiterplatte am äußeren Rand der Leiterplatte entlang geführt werden können, was Störeinflüsse auf die signalübertragenden Leiterbahnen der Leiterplatte minimiert.The direction of the width axis of the printed circuit board in this case is the direction in which the printed circuit board extends in the width, that is transverse to the longitudinal axis of the printed circuit board. The width axis can also be referred to as a transverse axis. In other words, the signal-transmitting female contacts between the outer, energy-transmitting female contacts are arranged on the circuit board. Advantageously, this arrangement makes it possible for the connecting conductors, which electrically conductively connect the energy-transmitting stranded contacts to the energy-transmitting jack contacts, to be guided along the outer edge of the printed circuit board in the direction of the width axis of the printed circuit board, which minimizes interference with the signal-transmitting printed conductors of the printed circuit board ,

Vorzugsweise ist eine Teilmenge der Litzen-Kontakte an der Oberseite der Leiterplatte angeordnet, und die verbleibende Teilmenge der Litzen-Kontakte ist an der Unterseite der Leiterplatte angeordnet.Preferably, a subset of the stranded contacts are located at the top of the circuit board and the remaining subset of the stranded contacts are disposed at the bottom of the circuit board.

Es ist möglich, dass die Hälfte der Litzen-Kontakte auf der Oberseite der Leiterplatte angeordnet ist, und die andere Hälfte der Litzen-Kontakte auf der Unterseite der Leiterplatte angeordnet ist. Ebenso ist ein anderes Verhältnis möglich. Es ist auch denkbar, das alle Litzen-Kontakte auf einer Seite der Leiterplatte, der Oberseite oder der Unterseite, angeordnet sind.It is possible that half of the stranded contacts are located on top of the circuit board and the other half of the stranded contacts are located on the underside of the circuit board. Likewise, another relationship is possible. It is also conceivable that all the stranded contacts are arranged on one side of the printed circuit board, the upper side or the lower side.

Vorteilhafterweise kann durch die Anordnung der Litzen-Kontakte auf der Oberseite und der Unterseite der Leiterplatte der Raum innerhalb des Gehäuses gut ausgenutzt werden. Ferner wird durch die Verteilung der Litzen-Kontakte die Zugänglichkeit der Litzen zu den Litzen-Kontakten verbessert.Advantageously, the space within the housing can be well utilized by the arrangement of the stranded contacts on the top and bottom of the circuit board. Furthermore, the distribution of the strands contacts improves the accessibility of the strands to the strands contacts.

Vorzugsweise sind an der Oberseite der Leiterplatte fünf Litzen-Kontakte angeordnet und an der Unterseite der Leiterplatte fünf Litzen-Kontakte angeordnet.Preferably, five stranded contacts are arranged on the upper side of the printed circuit board and five stranded contacts are arranged on the underside of the printed circuit board.

Vorteilhafterweise kann durch die Anordnung der jeweils fünf Litzen-Kontakte auf der Oberseite und der Unterseite der Leiterplatte der Raum innerhalb des Gehäuses gut ausgenutzt werden. Ferner wird die Zugänglichkeit der Litzen zu den Litzen-Kontakten verbessert. Durch die insgesamt zehn Litzen-Kontakte können beispielsweise acht signalübertragende Litzen eines standardisierten Netzwerk-Kabels sowie zusätzlich zwei energieübertragende Litzen jeweils mit den Litzen-Kontakten elektrisch leitend verbunden werden.Advantageously, the space within the housing can be well utilized by the arrangement of the five stranded contacts on the top and the bottom of the circuit board. Furthermore, the accessibility of the strands to the strands contacts is improved. For example, eight signal-transmitting strands of a standardized network cable as well as two additional energy-transmitting strands can each be electrically conductively connected to the strands contacts by means of the ten stranded contacts.

Die Litzen-Kontakte sind als Schneidverbinder ausgeführt.The stranded contacts are designed as cutting connectors.

Die Schneidverbinder können hierbei beispielsweise eine Y-förmige Gestalt aufweisen mit einem Pinbereich und zwei am Pinbereich angeordneten und sich vom Pinbereich erstreckenden Schneidschenkeln. Die Schneidschenkel können abschnittsweise parallel zueinander angeordnet sein und in einem Öffnungsbereich enden in dem sich der Abstand zwischen den Innenseiten der Schneidschenkel aufweitet. Der Abstand zwischen den Schneidschenkeln in dem Bereich, in dem die Schenkel parallel verlaufen, kann etwas kleiner sein, als der Durchmesser eines Leiters einer zu konnektierenden Litze. Konnektieren bedeutet hierbei, elektrisch leitend zu verbinden. Ein Schneidschenkel oder beide Schneidschenkel können einen Schneidenbereich aufweisen, der z.B. klingenartig gestaltet sein kann, sodass mit dem oder den Schneidschenkel(n) eine Isolierhülle der Litze durchschnitten und der Leiter der Litze in elektrisch leitenden Kontakt mit dem oder den Schneidschenkeln gebracht werden kann. Der Leiter kann zwischen den Schneidschenkeln eingeklemmt und so in Kontakt mit dem oder den Schneidschenkel(n) gehalten werden. Je nach Durchmesser der Litzen bzw. der Leiter der Litzen, können die Größen bzw. die Ausgestaltung der zugeordneten Schneidverbinder angepasst sein. So können beispielsweise sowohl signalübertragende Litzen als auch energieübertragende Litzen sicher mit den Schneidverbindern der zugeordneten signalübertragenden bzw. energieübertragenden Litzen-Kontakte elektrisch leitend verbunden werden.In this case, the cutting connectors may, for example, have a Y-shaped configuration with a pin area and two cutting legs arranged at the pin area and extending from the pin area. The cutting legs can be arranged in sections parallel to each other and end in an opening region in which the distance between the inner sides of the cutting legs expands. The distance between the cutting legs in the region where the legs are parallel may be slightly smaller than the diameter of a conductor of a strand to be connected. Connect here means to connect electrically conductive. A cutting leg or both cutting legs may have a cutting area, e.g. can be designed blade-like, so that with the or the cutting leg (s) cut through an insulating sheath of the strand and the head of the strand can be brought into electrically conductive contact with the cutting legs or. The conductor can be clamped between the cutting legs and held in contact with the cutting leg (s). Depending on the diameter of the strands or the conductor of the strands, the sizes or the configuration of the associated cutting connector can be adjusted. Thus, for example, both signal-transmitting strands and energy-transmitting strands can be securely connected to the cutting connectors of the associated signal-transmitting or energy-transmitting strands contacts electrically conductive.

Das Vorsehen von Schneidverbindern vereinfacht die Montage des Steckers, da ein Freilegen der Leiter der Litzen entfallen kann.The provision of cutting connectors simplifies the installation of the connector, since an exposure of the conductors of the strands can be omitted.

Der Stecker umfasst:

  • Litzenaufnahmeelemente, wobei die Litzenaufnahmeelemente in dem Gehäuse angeordnet sind und Litzenaufnahmeöffnungen aufweisen, wobei einzelne Litzen des Verbindungskabels in die Litzenaufnahmeöffnungen einführbar sind, und wobei die Litzenaufnahmeelemente auf der Leiterplatte über die Schneidverbinder stülpbar sind, um die einzelnen Schneidverbinder mit den einzelnen Litzen des Verbindungskabels elektrisch leitend zu verbinden.
The plug includes:
  • Litz receiving elements, wherein the Litzenaufnahmeelemente are arranged in the housing and have Litzenaufnahmeöffnungen, wherein individual strands of the connection cable in the Litzenaufnahmeöffnungen are insertable, and wherein the Litzenaufnahmeelemente on the circuit board via the cutting connector are turnable to electrically connect the individual cutting connector with the individual strands of the connecting cable.

Durch das Vorsehen von Litzenaufnahmeelementen kann die Montage des Steckers stark vereinfacht werden. Vorzugsweise weist der Stecker zwei Litzenaufnahmeelemente auf, wobei ein Litzenaufnahmeelement auf der Oberseite der Leiterplatte über die Schneidverbinder stülpbar ist, und das andere Litzenaufnahmeelement auf der Unterseite der Leiterplatte über die Schneidverbinder stülpbar ist. Hierbei werden die einzelnen Litzen, die in die Litzenaufnahmeöffnungen eingeführt sind, durch die Litzenaufnahmeelemente in Position gehalten, sodass beim Drüberstülpen der Litzenaufnahmeelemente über die Schneidverbinder die einzelnen Litzen automatisch mit den zugeordneten Schneidverbindern der Litzen-Kontakte elektrisch leitend verbunden werden.By providing Litzenaufnahmeelementen the assembly of the connector can be greatly simplified. Preferably, the plug has two strand receiving elements, wherein a strand receiving element on the upper side of the printed circuit board is slipped over the cutting connector, and the other strand receiving element on the underside of the printed circuit board is slipped over the cutting connector. Here, the individual strands, which are inserted into the Litzenaufnahmeöffnungen, held by the Litzenaufnahmeelemente in position so that when Drüberstülpen the Litzenaufnahmeelemente via the cutting connector, the individual strands are automatically connected to the associated cutting connectors of the strands contacts electrically conductive.

Vorzugsweise sind die Leiterbahnen der Leiterplatte im wesentlichen nicht parallel zueinander ausgestaltet, um gegenseitige Störeinflüsse zu minimieren.Preferably, the conductor tracks of the printed circuit board are configured substantially not parallel to each other in order to minimize mutual interference.

Die einzelnen Leiterbahnen der Leiterplatte können beispielsweise mit einem vorgegebenen Winkel zueinander bzw. schräg zueinander angeordnet sein. Die Leiterbahnen können sich auch überkreuzen, wobei die Leiterbahnen zumindest in dem Überkreuzenden Bereich zueinander isoliert sind, und/oder es können parallel Verlaufende Abschnitte der Leiterbahnen mit größtmöglichem Abstand zueinander angeordnet sein.The individual conductor tracks of the printed circuit board can be arranged, for example, at a predetermined angle to one another or at an angle to one another. The interconnects may also cross over, the interconnects being insulated from one another at least in the cross-over region, and / or parallel-extending sections of the interconnects may be arranged with the greatest possible distance from one another.

Vorteilhafterweise werden dadurch, dass die Leiterbahnen der Leiterplatte im wesentlichen nicht parallel zueinander verlaufen, gegenseitige Störeinflüsse der Leiterbahnen untereinander minimiert, was zu einer verbesserten Signalqualität und somit zu einer verbesserten Leistungsfähigkeit des Steckers führt. Insbesondere kann die Leiterplatte für eine verbesserte Signalqualität optimiert ausgelegt und gefertigt werden.Advantageously, the fact that the printed conductors of the printed circuit board do not run substantially parallel to one another minimizes mutual interference between the printed conductors, which leads to improved signal quality and thus improved performance of the connector. In particular, the printed circuit board can be designed and manufactured optimized for improved signal quality.
